Specifications of Rectangle Alumina Ceramic Boats Crucible

These alumina ceramic watercrafts are workhorses for high heat jobs. They handle severe temperatures without fracturing. You get trusted performance set after set. These boats can be found in basic sizes. Common lengths are 100mm, 150mm, 200mm, 250mm, 300mm. Widths normally vary from 30mm to 80mm. Depths are generally 10mm, 15mm, or 20mm. Customized dimensions are feasible. Wall surfaces are thick, generally 3mm to 6mm. This thickness provides stamina. It stops contorting under intense warm. The material is high-purity alumina. Standard pureness is 99.6% Al2O3. Higher pureness alternatives like 99.8% exist. High pureness indicates less contamination. Your products remain cleaner. These boats withstand very high temperatures. Limit continuous use temperature is 1600 ° C. Short spikes to 1700 ° C are alright. They will not thaw or degrade. Thermal shock resistance is outstanding. Moving watercrafts from hot to chilly areas is secure. They will not break easily. Alumina is extremely difficult. It is difficult against abrasion. Particles won’t conveniently scrape the surface. Chemical resistance is strong. Acids and alkalis don’t damage the boats. Rough process atmospheres are not a problem. The surface coating is smooth. This prevents material sticking. It makes cleaning simpler. Monotony is securely regulated. Watercrafts sit level in furnaces. Heat transfers evenly. These boats are excellent for sintering. They work for annealing. They are perfect for warm treating. They are utilized in powder calcination. Semiconductor handling relies on them. Laboratory heating systems utilize them continuously.

5 FAQs of Rectangle Alumina Ceramic Boats Crucible

What are rectangle alumina ceramic boats made of?
They use high-purity alumina ceramic. This material is very strong and lasts a long time. It is 99.6% pure aluminum oxide. This purity matters for consistent performance.

How hot can these ceramic boats get?
They handle very high temperatures well. Maximum continuous use is 1650°C (3002°F). They also resist sudden temperature changes. This means they won’t crack easily when heated or cooled fast.

Where are these ceramic boats mostly used?
They are common in high-temperature furnace work. You see them often in labs and factories. They are good for sintering, annealing, and brazing processes. They are popular in semiconductor and materials research.

Can I clean these boats after use?
Yes, cleaning is possible. Use common lab cleaning methods. Soak in solvents or acids like acetone or nitric acid. Scrub gently with a soft brush. Rinse well with water. Avoid rough tools that scratch.

Are there handling precautions?
Handle them carefully. Alumina ceramic is hard but brittle. It can break if dropped or hit hard. Always place them on a flat, stable surface. Avoid bumping them against other hard objects. Store them safely when not in use.
